ing tongs for the hair. The usual form of gas heater-for hair curling tongs or curler consists,

merely of a'burner and a rack on which to'rest 'thencurler. It is necessary to keep'the burner "going all during the hair curling operation regardless ofzwhether' the curler is being heated,

used" on the hair or cooled. This is very uneconomical. The principal object of this invention is m to; economize inthe use of the gas, and it is characteristic of the invention that when the 4 Icurler is placed in the holder the burner is lit, and 1 when the curler'is lifted ofi,the burner is shut I 25 taken on theline 3,'3of Fig. 2.

v In order to devise, an automatic gas cut-oil? andlighter for Ja -hair Icurler, I have found that -it is necessary to make use of the full'weight of the curler acting against a tension spring of appreciable strength to control the gas cock, and

Y Y it is also necessary to turn the gas cook through 1 a considerable arc for the usual opening and 1 closing movement. With these facts in mind, I

w w 1' fhave devised the following heater.

1 35: The burner consists of a horizontal perforated jpipe'5 screwed on the air intake 6, the latter being 'attached to the gas supply through the gas cook V 8; The burner is long enough to heat the tongs of the curler. Projecting upwardly from the gas 1 F cock 8 but between the cock proper and the gas supply I, ma screw valve! for a gas pilot light II). It will be noted that the pilot is never shut off. 7 The pilot extends above the. air intake .toa position above the holes II in the burner 5.

It should. be understood that any other desired 7 type of pilot light such as a friction type of lighter actuated by the operatingarm described below, can be used. Also, a chemical type of pilot can be used.

- 50 Surrounding the burner is a hollow rectangular [holder or frame l2 which-may be openrat the bottom. The burner extends longitudinally I therein near the bottom and is held by a set screw l3. It will be noted that the burnerprefa 55 erably' is not centrally located but is adjacent one curler when it is to be heated, the frame has a very close to the center of gravity of the latter,

I 7 (c1. lee-23 4) Thisinventlon relates to a gasheater for curl-' side of the'framel The upper end and side portions l4, 15 of the frame may be sloped inwardly a little, as shown in the drawing, if desired. The topof the frame is preferably flat. To receive the slot cut in it from end to end above the burner 5. This slot provides rests l6, I! at the gas supply end and the outer end respectively of the frame, and the proper distance above the burner to heat the curler. Theserests are about the level 10 where the sloping upper portions I of the ends join the vertical portions. The slot is wide enough to take the tongs it of the curler but not .thecenter l9 about which the tongs pivot. The

p center ofgravity of the ordinary curler is at or about this hinge center l9. To get the benefit of where itsend underlies the curler adjacent the rest IT, at the opposite or free end of the burner from the gas cock. This brings the point of contact between the operating arm and the curler and as aresult'practically the entire weight of the curler rests on the arm. It will be noted that the bend in the handles of the ordinary curler prevents the curler from being inserted so far in the heater as to lose the full benefit of the weight of the curler to control the gas cock. A tension spring 2| connected between the arm and the. under side of the top of the frame is capable of pulling the arm 20 upwardly and operating the gas cook to close it. The weight of the curler is suflicient to open the gas cook against the pull of the spring.

.It will be observed that owing to the length of arm necessary to reach the center of gravity of the curler, a considerable movement of the end of the arm is needed to operate the gas cook. For this reason the end of the arm underlying the curler is bent upwardly in the form of a high step 22 adapted to project upwardly through the slot when the curler is removed. (See the solid line position in Fig. 1.) Owing to this high step when the curler is laid in the slot the arm is depressed all the way to the bottom of the frame, this giving the maximum travel. (See the dotted line positionin Fig. l.) The flat top of the frame is adapted to form a rest for the curler when not in use or when cooling.

To use the heater the screw valve 9 is opened, the pilot lighted and that flame adjusted. The

curler is then brought above the heater with the end of the tongs toward the gas cock and lowered onto the high step 22 and the rests IS, IT. The pivot center IQ of the curler should be placed adjacent the corresponding sloping end M of the frame. The depressing of the operating arm 20 by the weight of the curler opens the gas cook 8 and the pilot l0 lights the burner 5. When the curler is needed it is lifted out of the slot and off the high step of theoperating-arm. The tension spring thereupon operates the arnish) to close the gas cock and the flow of gas to the burner is stopped. The pilot light remains on. Obviously with this automatic cut-off only gas for the pilot light is burned except when the curler is to be heated.

What I claim is: I 1. A gas heater for a hair curlerycomprising a frame having a slot therein to receive the curler,-

a burner mounted under the slot and a gas cook adjacent one end of theframein combination with an operating arm :for the gas cook having a portionlying' inthe slotiat a point beyond the burner and adapted to be depressed .when the curler is 'placed in the. slot. 1

2. A gas heater for awhair curler,- comprising a frame having a slottherein to .receiveithe curler, a burner mounted under the slot and a gas cook adjacent one endof' the frame, in combination with an operating armrcarr-ied'bytheigas cock extending beside the-burner, and a tension spring tending to'keep the arm in raised-position, there being a high step on" the armprojectingiupwardly through the slot above the frame and adapted to be depressed when the curler isplacedoverthe burner. r r

3. A gas heater fora hair curler, comprising a frame having a slot therein to receive the curler, a burner mountedunder' the slot and a gas cook adjacent one end of t'heframe, incombination with an operating'arm carriedby: the

gas cock extendingbeside the burner, and a tension spring tendingto keepfthe arm-in raised position, there being a high stepon thearm-p'rojecting upwardly through the slot above 'the f rame at a point beyond'the holes in the bur'nerxand adapted to be depressed when the curlerisplaced over the burner.

4. A gas heater for a hair curler, comprising a gas cook, an operating arm attached to the cock and a burner on said cock, in combination with a frame having a slot therein over the burner forming rests for the curler between the burner and the cock and also beyond the free end of the burner, said slot'being too narrow to receive the hinge point of the ordinary curler, said operating arm being adapted to contact the curler beyond the free end of the burner and to be actuated thereby to open the cock, and a tension spring to actuate the arm in the opposite direction upon removal of the curler.

5. A gas heater for a hair curler, comprising a frame-having a slot therein to receive and form .rests for the curler, a burner mounted under the slot and a gas cock adjacent one end of the frame, in combination with an operating arm carried by the gas cook and a tension spring tending to keep,

the arm in raised position, there being a high "step on the arm projecting vupwardlyabove the frame beyond thefree end-of thetburner and. adapted to be depressed to thelevel of the rests in the frame when the curler is placed over the burner, the slot in the frame being too narrow to receive the hinge point of the ordinary curler whereby the point of contact between the'step on the'arm and the curler will be close' to the center of gravity of the latter.

6. A 'gas heater for a hair curler, comprising a gas cock, a-burner on-said'cock and an operating arm attached to the cock; inxcombination with a fiat-top frame having a slot thereinover the burner, said slot being too narrow to receive the handles of the ordinary curler, 'theoperating armbeing adapted to contact the curler beyond the free end of the burner and to lee-actuated thereby to open the cock, and a tension spring to actuate said arm in theopposite direction upon removal of the curler, said frame forming one rest 1.

for the curler between the cockand the burner and another rest sufficiently'beyondthe free end of the burner to be. close to thecenter of gravity of the curler'and therebyavoid the necessity for any support beyond the frame.
